AUXILIARY TOOL SUPEPORT.

Application filed October 8, 1921. Serial No. 506,401.

To all whom it may concern:

Be it known that I, JAMns K. CULLEN, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Auxiliary ToolSupports, of which the following is a specification.

This invention relates to boring mills and like machines andparticularly to an auxiliary tool supporting column adapted to beremovably secured to the bed of the machine and to extend upwardlyadjacent the table thereof. In machines of this type a supplemental toolfor performing certain operations on the work is often of considerableadvantage. It is accordingly a primary object of the invention toprovide in combination with a boring or like machine an auxiliary toolsupporting column adapted to be removably and rigidly secured to the bedof the machine beneath the work table and to extend preferably in avertical direction to one side of and above the table in a manner tosupport a tool thereon in a work engaging position.

Another object of the invention is to provide an auxiliary tool supportfor boring mills and the like comprising a base portion adapted to beremovably and rigidly secured to the bed of a boring mill, 2. columnportion, tool supporting means on the column and means for feeding thetool vertically and horizontally either simultaneously or independentlyas desired.

lVith these and other objects in view, my invention consists in thefeatures of construction and operation setforth in the followingspecification' and illustrated in the accompanying drawing. In "suchdrawing annexed hereto and forming a part of this specification, I haveshown certain embodiments of my invention as applied to a boring millbut it will be understood that the invention can be otherwise embodiedand that the drawing is not to be construed as defining or limiting thescope of the invention, the claims appended to this specification beingrelied upon for that purpose.

Referring to the figures of the drawing:

Figure 1 is a partial front elevation of a boring mill having thepresent invention applied thereto.

Fig. 2 is a fragmentary side elevation thereof.

As stated above, the object of the inven tion is to provide an auxiliarytool support for boring mills or like machines. The construction of thesupport is preferably in the form of a column having a base adapted tobe mounted on and secured to a pad or check formed on the bed of themachine. Except for such pad or cheek, the construction of the machinepreferably remains unaltered. The cost of providing this cheek onstandard machines, as manufactured, is negligible but fully equips allsuch machines for receiving the auxiliary tool support thereon.Furthermore, the expense of such additional equipment to the shop iscomparatively small since a single attachment ordinarily is sufiicientto care for several machines. It may furthermore be stated that theauxiliary support is so mounted on the machine that it in no Wayinterferes with the usual operation thereof.

Referring more specifically to the figures of the drawing by referencecharacters, 1 indicates the bed of a boring mill, 2 the retary tablethereon and 3 and t the usual vertical uprights on thebed. A cross rail5 with tool supports 7 and 8 thereon, as illustrated, is mounted on theuprights. The subject matter of the present invention is an auxiliarytool supporting column particu larly adapted to be used in combinationwith a machine of the type just described, such auxiliary column withthe tool supporting and operating means combined therewith beingillustrated in the drawing as removably secured to a pad or cheekon thebed 1: This auxiliary construction will now be des. scribed. 1 5

r The auxiliary tool. supporting column com! prises a base 10 having acolumn 11 extend ing preferably vertically therefrom to a po sitionadjacent and above the table 2. The bed 1 of the boring mill isillustrated as provided with a check sponding supporting portion 13 ofthe base 10 is secured. Bolts 14: and a tongue and groove connection 15serve to rigidly secure the auxiliary tool support to the bed 1.

A tool supporting saddle 16 is vertically slid-able on the column 11 anda tool bar 17 is nioin'ited for horizontal sliding movement on thesaddle, preferal'ily radially of the table 2. It will be understood thatthe saddle and tool bar can be fed on their re spcctive supports in anymanner and by any 12 to which the corremeans desired. In the drawing, Ihave illustrated such members as being fedfrom a feed motor 18.

A screw 19 and a feed shaft 20 are mounted Vertically in the column 11.The screw engages a nut 21 on the saddle for moving the saddlevertically. The feed shaft is operatively connected to a rack 22 on thetool bar through a train of gearing 23, 24, 25 and 26 and a pinion 27,the gear 23 being splined to the feed shaft and the pinion 27 engagingthe rack for axially moving the bar horizontally in the saddle,preferably ra dially of the table 2.

A horizontal shaft 28 is operatively connected to the motor throughintermeshing spur gears 29 and 30. Bevel gears 31 and 32 loose on theshaft 28 are respectively in mesh with bevel gears 33 and 34 on thescrew and feed shaft. Bevel gears 31 and '32 each extend through asupporting bearing and are provided with clutch portions 35 and 36respectively on the other ends thereof. Clutches 37 and 38 are sp-linedto the shaft 28 and are adapted to be shifted therealonlg to engage theclutch portions 35 and 36 respectively to drive the screw and feed shaftfrom the motor. Hand levers 39 and 4.0 are provided for shifting theclutches 37 ant 38.

Briefly, the operation of the machine is as follows: When the operatordesires the use of an auxiliary tool, as heretofore stated, he securesthe auxiliary tool supporting column to the cheek 12 of the boring millor like machine. The saddle 16 may then be moved vertically to thedesired elevation by means of the motor 18, screw 19 and theintermediate connections heretofore described. The tool bar 17 also maybe moved horizontally in the saddle to the desired position through thefeed motor and the operative connections therefrom to the rack 22.IVit-h the tool thus set to the proper position, the same may be fed inthe tooling operation either horizontally or vertically or both throughthe before described feeding connections from the motto It will beunderstood that the feeding operation of the motor may controlled in theusual manner. By referring to Fig. 2, it will be seen that the auxiliarycolumn 11 is sufiicientl 7 spaced from the main column 4 to avoid anyinterference with the cross rail and the tool supports thereon. Theauxiliar r tool supporting means therefore operates to perform thedesired function without in any way interfering with the usual andnormal oper ation of the machine. For the reason last stated, it mayoften be desirable to use this auxiliary tool supporting means in lieuof the usual side head mounted on one of the main uprights beneath thecross rail. As is well known, such side head positively prevents thelOWQliDig' of the cross rail to, its lowermost position on the uprights.

What I claim isf r 1. In a boring mill, the combination of a bed, a worktable rotatably mounted thereon, a vertically extending upright adjacentthe table, tool supporting means carried by the upright, the bed beingprovided with a supporting check on one side thereof, an auxiliary too-lsupporting column removably and rigidly secured to the said check on thebed of the machine beneath the work table and extending upwardly to aposition ad acent and above the table, a tool supporting saddle carriedby the column, a tool holder carried by the saddle, and means for movingthe saddle along the column and the tool holder in the saddle.
